I am asking because I am thinking about going to Fry's electronics and exchanging the other stick, but it is a long drive so I am curious what I should realistically expect before I bother doing so.

Also would it be faster to run CAS 4 at 800 or CAS 6 at 1098?
The only way to know is to give it a try. Try some settings and test em in Sandra and maybe 3DM06 or a game benchmark. I found over 900Mhz on the memory the bandwidth starts to drop off a bit and there was no 'real-world' performance gain. But with a stock memory clocks (800) and tighter timings some games and apps are a little faster. The differences are quite small though really. I'd say go for CAS4 @ 800Mhz. Also running in 'Sync mode' gave me a boost of about 500Mb/s with the memory.
